/* ** ** Swift/XRT hardness ratio for Mrk 501. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 58711.980028 0.000472 0.26989 0.04341 0.95706 0 2.77582 0.20794 2.36718 0.17734 0.74917 0.10662 0.63856 0.09087 58711.981147 0.000648 0.19381 0.03016 0.97768 0 2.73167 0.17196 2.34813 0.14780 0.52942 0.07535 0.45486 0.06473 58711.982389 0.000593 0.20111 0.03216 0.98537 0 2.78466 0.18162 2.39794 0.15639 0.56002 0.08175 0.48221 0.07039 58711.983439 0.000457 0.28228 0.04567 0.98734 0 2.62826 0.20232 2.26179 0.17411 0.74191 0.10558 0.63856 0.09087 58711.984382 0.000486 0.26863 0.04365 1.00000 0 2.55083 0.19591 2.19511 0.16859 0.68522 0.09813 0.58966 0.08445 58711.985311 0.000443 0.31531 0.05177 0.98039 0 2.44636 0.20031 2.10680 0.17250 0.77137 0.10978 0.66410 0.09451 58711.986616 0.000862 0.24220 0.02917 0.94459 0 3.00890 0.16546 2.59051 0.14245 0.72877 0.07807 0.62753 0.06723
